Description

Technical Field

[0001] This invention relates to the field of material aging testing technology, and more specifically, to a high-altitude sensor terminal material aging testing system. Background Technology

[0002] As power systems and communication networks continue to extend into extreme geographical environments such as plateaus and high altitudes, the long-term reliability and data accuracy of various sensing terminals deployed in these environments—such as sensors used to monitor icing on transmission lines, equipment temperature, or changes in air pressure—are facing increasingly severe challenges. High-altitude regions typically exhibit characteristics such as low air pressure, significant temperature differences, strong ultraviolet radiation, and variable weather conditions. These environmental stresses significantly accelerate the aging process of critical materials such as the sensor terminal's casing, seals, and internal circuit boards, potentially leading to sensor signal drift, insulation failure, or even complete device damage, ultimately threatening the safe and stable operation of the entire system. Therefore, accelerated aging tests on sensing terminals in high-altitude environments to assess their material adaptability and lifespan in advance have become an indispensable part of related product development and quality verification.

[0003] Currently, the technical solutions used in the industry for material aging tests are mainly based on simulation testing equipment for single or a few types of environmental stresses. For example, constant temperature and humidity chambers or high and low temperature alternating chambers are used to cyclically age the test samples, or ultraviolet aging chambers are used to simulate the damage caused by ultraviolet radiation in sunlight to materials, or low-pressure test chambers are introduced to reproduce the negative pressure conditions at high altitudes. When conducting these tests, operators usually need to put the sample to be tested into the test chamber, set the operating parameters, and wait for the test cycle to end before taking out the sample for subsequent performance testing or data recording. If the sample needs to undergo aging tests with multiple different stresses in sequence, the above operations need to be repeated many times, which has obvious shortcomings in efficiency and automation. More importantly, the synergistic effect of multiple parameters such as air pressure, temperature, humidity and ultraviolet radiation unique to high-altitude environments is difficult to be synchronously and accurately reproduced in existing conventional equipment. Therefore, it is often difficult to truly simulate the comprehensive aging effect of sensing terminals under actual high-altitude working conditions, which greatly reduces the guiding value of test data for product life prediction.

[0004] Therefore, there is an urgent need for a new type of testing system that can achieve fully automated operation, coordinated loading of multiple environmental stresses, and flexible execution of complex aging tasks. Summary of the Invention

The control unit is used to generate a first control command to control the side-push mechanism, a second control command to control the loading and unloading robot, and a third control command to control the actuator according to the test task. The first control command instructs the side-push mechanism to open or close the corresponding cover, the second control command instructs the loading and unloading robot to place the sensor terminal on the corresponding shelf or transfer the sensor terminal on the corresponding shelf to the next work station, and the third control command instructs the actuator to reproduce the corresponding environmental parameters in each environmental simulation chamber.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Example 1 This invention provides a high-altitude sensor terminal material aging test system. Figure 1 This is a schematic diagram of the overall structure of the experimental system, as shown below. Figure 1 As shown, the test system includes a main frame 100, a conveying unit 200, a test unit 300, and a control unit. The units cooperate with each other to realize the fully automated operation of the sensing terminal from feeding, transfer, environmental loading to discharging.

[0020] Specifically, the main frame 100 adopts a spatially layered steel structure frame form, which has a first mounting section on the upper layer, a second mounting section on the lower layer, and several third mounting sections located on the side of the second mounting section. The first mounting section is mainly used to install and support the relevant components of the conveying unit 200, the second mounting section serves as a test area to accommodate the various environmental simulation chambers 310, and the third mounting sections are located on the side of the second mounting section to accommodate the side-pushing mechanism 320 that drives the opening and closing of the chamber body 311 cover 312.

[0021] As an optional implementation, the main frame 100 can be specifically composed of a cross-shaped main beam 110. A first longitudinal beam 120 is vertically arranged downward in the middle of the cross-shaped main beam 110, and a second longitudinal beam 130 is vertically arranged downward at each of the four ends of the cross-shaped main beam 110. The lower ends of each second longitudinal beam 130 are connected to each other by a crossbeam 140, thereby forming a stable cage-like frame structure. Based on this structure, the first mounting part is located in the lower space of the cross-shaped main beam 110, the second mounting part is located in the peripheral space of the first longitudinal beam 120, and the third mounting part is located in the inner space of each second longitudinal beam 130. The above-mentioned layered layout not only provides clear installation positions for each functional component, but also provides sufficient movement space for the subsequent loading and unloading robot 220 to slide along the guide rail 210 to pick up and place samples.

[0022] The conveying unit 200 is mainly responsible for transferring the sensing terminals between various workstations. The conveying unit 200 has a guide rail 210 installed in the first mounting section and a loading / unloading robot 220 slidably fitted onto the guide rail 210. The guide rail 210 is horizontally arranged on the upper layer of the main frame 100, and its overall orientation corresponds to the arrangement of the environmental simulation chambers 310 below. The loading / unloading robot 220 is slidably mounted on the lower end face of the guide rail 210 and can move along the trajectory of the guide rail 210 under the control of the control unit. Move to the designated position and perform vertical lifting and gripping actions after reaching the target position; in some preferred embodiments, the loading and unloading robot 220 can use pneumatic grippers or electric grippers as end effectors to adapt to sensor terminal samples of different shapes and sizes; in addition, the layout height of the guide rail 210 must ensure that the loading and unloading robot 220 can reach the shelf placed in the environmental simulation chamber 310 when it is fully descending, and can avoid the opening and closing movement path of the cover 312 of each chamber 311 when it is fully rising.

[0023] The test unit 300 has several environmental simulation chambers 310 disposed in the second mounting part and a side push mechanism 320 disposed in the third mounting part; each environmental simulation chamber 310 is equally spaced below the guide rail 210, that is, each environmental simulation chamber 310 is located in the orthographic projection area of ​​a certain horizontal section of the guide rail 210, so that the loading and unloading robot 220 can slide along the guide rail 210 to the position above any environmental simulation chamber 310 and perform sample loading and unloading operations in the chamber.

[0024] As an optional implementation, each environmental simulation chamber 310 consists of three parts: a chamber body 311, a cover 312, and a shelf. The chamber body 311 is a box-shaped structure with an opening on one side, and its internal space is used to form a closed test chamber. The cover 312 is opened and closed on the side of the chamber body 311. Preferably, the cover 312 is opened and closed by lateral translation relative to the chamber body 311, rather than a traditional top-opening or front-opening structure. The output end of the side-pushing mechanism 320 is connected to the side of the cover 312 facing away from the chamber body 311. The side-pushing mechanism 320 is used to drive the cover 312 to perform opening or closing actions after receiving a control command. The shelf is set in the space between the compartment 311 and the cover 312. Specifically, it can be fixed to the inner side of the bottom wall of the compartment 311 or integrally formed with the compartment 311, and is used to carry the sensor terminal sample to be tested. The upper surface of the shelf can be provided with positioning grooves or positioning pins to ensure that the sensor terminal has a definite placement position on the shelf, so as to facilitate the precise picking and placing operation of the loading and unloading robot 220.

[0025] In addition, each environmental simulation chamber 310 is equipped with one or more actuators of different types, which are used to generate and maintain specific environmental stress conditions inside the chamber 311. Specifically, the actuators may include various types such as temperature control modules, humidity control modules, air pressure control modules, ultraviolet LED arrays, and wind speed control modules.

[0026] The temperature control module can combine heating wires and compressor refrigeration to achieve heating and cooling functions; the humidity control module can use an ultrasonic humidifier and a condenser dehumidifier to regulate humidity; the air pressure control module can use a vacuum pump and an intake valve to reduce and restore air pressure inside the chamber; the ultraviolet LED array can be installed on the top or side wall of the inner wall of chamber 311 to emit ultraviolet light of a specific wavelength to simulate the strong radiation environment of high altitude; the wind speed control module can use a small axial flow fan and a guide plate to form a circulating airflow inside the chamber. The actuator types configured in each environmental simulation chamber 310 can be differentiated according to actual test requirements. For example, the first environmental simulation chamber 310 is equipped with three actuators for temperature, humidity, and air pressure to simulate basic high-altitude climate conditions, while the second environmental simulation chamber 310 additionally adds an ultraviolet LED array to simulate aging scenarios under strong ultraviolet radiation.

[0027] As an optional implementation, the control unit generates a first control command to control the side-pushing mechanism 320, a second control command to control the loading / unloading robot 220, and a third control command to control each actuator according to a pre-set test task. The first control command instructs the side-pushing mechanism 320 to open or close the cover 312 of the corresponding environmental simulation chamber 310, automatically opening the environmental simulation chamber 310 when the loading / unloading robot 220 needs to pick up or place samples, and ensuring a tight seal between the cover 312 and the chamber 311 during the test. The second control command instructs the loading / unloading robot 220 to slide along the guide rail 210 to the target position and place the sensor terminal on the corresponding shelf, or to remove the sensor terminal that has completed a certain stage of aging test from the corresponding shelf and transfer it to the next workstation, such as to another environmental simulation chamber 310. The next stage of aging test can be carried out, or the test process can be ended by transferring to the unloading station; the third control command is used to instruct each actuator to reproduce the set environmental parameters in its corresponding environmental simulation chamber 310, such as adjusting the temperature in the chamber to -25℃, the humidity to 30%RH, and the air pressure to 70kPa in the first time period, and switching to the high temperature and high humidity and ultraviolet irradiation superposition mode in the second time period; the control unit can use an industrial programmable logic controller (PLC) or an embedded industrial computer as the hardware platform, and is equipped with a touch screen human-machine interface for operators to input test task parameters and monitor the system operation status.

[0028] When the system is being tested, if the sensor terminal needs to undergo two different stress conditions in sequence, namely low temperature and low pressure aging and high temperature and high humidity coupled ultraviolet aging, the control unit first generates a corresponding sequence of execution instructions based on the test task. Specifically, after the loading and unloading robot 220 picks up the sensor terminal to be tested from the loading station, the control unit issues a second control instruction to make the loading and unloading robot 220 slide along the guide rail 210 to the top of the first environmental simulation chamber 310. Then, the control unit issues a first control instruction to make the side push mechanism 320 corresponding to the chamber drive the cover 312 to open. Then, the loading and unloading robot 220 places the sensor terminal on the shelf in the chamber and exits the chamber 311. The control unit then issues a first control instruction to make the side push mechanism 320 drive the cover 312 to close. Then, the control unit issues a third control instruction to make the temperature control module, humidity control module and air pressure control module in the chamber run according to the set curve to complete the low temperature and low pressure aging stage test. After this stage, the control unit issues the first control command again to open the cover 312. Under the action of the second control command, the loading / unloading robot 220 removes the sensing terminal and transfers it along the guide rail 210 to the top of the second environmental simulation chamber 310. The process of opening, placing, closing the cover, and reproducing environmental parameters is repeated. Inside the second environmental simulation chamber 310, the temperature control module, humidity control module, ultraviolet LED array, and wind speed control module are activated to perform the high-temperature and high-humidity coupled ultraviolet irradiation aging stage. After all test stages are completed, the loading / unloading robot 220 removes the sensing terminal from the last environmental simulation chamber 310 and transfers it to the unloading station, thus completing the entire aging test process.

[0029] Furthermore, the guide rail 210 installed in the first mounting section can be a ring-shaped guide rail 210. This ring-shaped guide rail 210 is arranged around the periphery of the first longitudinal beam 120, and its trajectory is roughly rectangular or circular. The ring-shaped guide rail 210 allows the loading / unloading robot 220 to pass through each environmental simulation chamber 310, as well as the loading and unloading stations, along the circumferential path, thereby achieving flexible scheduling between multiple stations. When using the ring-shaped guide rail 210, the number of environmental simulation chambers 310 is preferably two or more. These environmental simulation chambers 310 are arranged at equal intervals along the extension direction of the ring-shaped guide rail 210 to ensure that the movement of the loading / unloading robot 220 between each station is uniform and controllable.

[0030] In one specific implementation of this embodiment, two environmental simulation chambers 310 are preferably configured within the second mounting section, and these two environmental simulation chambers 310 are symmetrically distributed on both sides of the first longitudinal beam 120 along the first direction; as shown... Figure 2As shown, with the first longitudinal beam 120 as the axis of symmetry, two environmental simulation chambers 310 are respectively set on the left and right sides of this axis, with both equidistant from the first longitudinal beam 120. This symmetrical layout not only facilitates the overall force balance of the main frame 100, but also shortens the transfer path length of the loading / unloading robot 220 between the two environmental simulation chambers 310, thereby helping to improve experimental efficiency. In this layout, the side of the chamber body 311 of each environmental simulation chamber 310 facing away from the cover 312 is fixedly connected to the side of the first longitudinal beam 120, for example, by welding or bolting to fix the rear wall of the chamber body 311 to the first longitudinal beam 120. This ensures the positional stability of the chamber body 311 under the repeated force of the side pushing mechanism 320, and also allows the chamber body 311 to resist the reaction force generated during the opening and closing of the cover 312 with the help of the first longitudinal beam 120 as a rigid support.

[0031] Regarding the specific structure of the side-pushing mechanism 320, when the environmental simulation chamber 310 is symmetrically arranged along the first direction, the second longitudinal beams 130 located on both sides of the first direction are respectively provided with grooves 131 in the vertical direction; the side-pushing mechanism 320 is composed of a drive motor, a threaded rod 321, a first drive block 322, a second drive block 323, a first connecting rod 324, and a second connecting rod 325. The threaded rod 321 is vertically arranged inside the grooves 131 of the second longitudinal beam 130, and the upper end of the threaded rod 321 is connected to the output end of the drive motor. The drive motor can be fixed to the top of the second longitudinal beam 130 or through a bracket. Mounted on the cross-shaped main beam 110; the threaded rod 321 has a first section and a second section with the thread direction opposite to that of the first section, i.e., the thread directions of the first section and the second section are opposite to each other; the first drive block 322 is threadedly connected to the first section of the threaded rod 321, and the second drive block 323 is threadedly connected to the second section of the threaded rod 321. Both the first drive block 322 and the second drive block 323 form a sliding fit with the inner wall of the slide groove 131, so that the two drive blocks can only slide vertically up and down and cannot rotate with the threaded rod 321. In the vertical position, the first drive block 322 is located at the... Above; the first end of the first connecting rod 324 is hinged to the first driving block 322, and the second end of the first connecting rod 324 is hinged to the upper end of the outer arc surface of the cover 312. The first end of the second connecting rod 325 is hinged to the second driving block 323, and the second end of the second connecting rod 325 is hinged to the lower end of the outer arc surface of the cover 312. When the drive motor drives the threaded rod 321 to rotate in the forward direction, since the first and second segments of the thread are in opposite directions, the first driving block 322 and the second driving block 323 will move towards each other along the slide groove 131 and approach each other. At this time, the first connecting rod 324 and the second connecting rod 325 respectively push the outer arc surface of the cover 312. The upper and lower ends of the push mechanism cause the cover 312 to move laterally relative to the compartment 311, thereby closing the cover 312. Conversely, when the threaded rod 321 rotates in the opposite direction, the two drive blocks move away from each other and pull the cover 312 through the first link 324 and the second link 325, thereby opening the cover 312. The push mechanism 320 has a compact structure and a large driving force, which can realize reliable opening and closing control of the cover 312 in a limited space. Furthermore, through the stroke amplification of the linkage mechanism, the drive motor only needs a small rotation angle to achieve a large translation distance of the cover 312, which is beneficial to improving the response speed.

[0032] In addition, a feeding conveyor belt 400 and a discharging conveyor belt 500 are respectively installed on the inner side of the second longitudinal beam 130 on both sides of the second direction. The second direction is another horizontal direction perpendicular to the first direction. The conveying end of the feeding conveyor belt 400 and the conveying beginning of the discharging conveyor belt 500 are both located directly below the annular guide rail 210, so that the loading and unloading robot 220 can directly grab the sensor terminal to be tested at the end of the feeding conveyor belt 400 and accurately place the sensor terminal at the beginning of the discharging conveyor belt 500 after completing all tests to enter the next process. The feeding conveyor belt 400 and the discharging conveyor belt 500 can be selected as synchronous belt conveyor structures, and their conveying directions can be set to the same horizontal direction to connect with the production lines of upstream and downstream processes, thereby realizing batch continuous test operations.

[0033] To ensure the airtightness of the environmental simulation chamber 310 during the test, sealing strips are embedded on the adjacent sides of the chamber body 311 and / or the cover 312. Specifically, the sealing strips can be embedded in the groove at the edge of the opening of the chamber body 311, or in the groove on the inner periphery of the cover 312, or sealing strips can be provided on both the edge of the opening of the chamber body 311 and the inner periphery of the cover 312 to form a double sealing effect. The sealing strips should preferably be made of silicone rubber or fluororubber materials that are resistant to high and low temperatures and ozone to ensure that they can maintain good elastic deformation capacity and sealing performance in the temperature range of -40℃ to +85℃ and under low pressure conditions, thereby preventing deviations in the environmental parameters inside the chamber due to leakage.

[0034] In summary, the high-altitude sensor terminal material aging test system provided in this embodiment, through the layered and partitioned arrangement of the first, second, and third mounting sections, and combined with the coordinated scheduling of the side-pushing mechanism 320, the loading and unloading robot 220, and various actuators by the control unit, can achieve automatic loading, automatic opening and closing of the chamber door, automatic placement and removal of samples, and automatic transfer to the next station of the sensor terminal in a highly automated manner throughout the entire aging test process, thereby significantly reducing the degree of manual intervention and improving test efficiency. Because the cover 312 adopts a side-opening and closing structure and is driven by the side-pushing mechanism 320, and in conjunction with the multiple environmental simulation chambers 310 evenly spaced below the guide rail 210, the upper and lower... The material handling robot 220 can sequentially perform pick-and-place operations on different environment simulation chambers 310 within the sliding stroke of the guide rail 210, thereby efficiently supporting the sequential or parallel aging tests of the sensing terminal under different environmental stress conditions. Each environment simulation chamber 310 is equipped with one or more different types of actuators, and is uniformly instructed by the control unit to reproduce the comprehensive high-altitude environmental stress, including multiple parameters such as temperature, humidity, air pressure, ultraviolet radiation and wind speed, within the corresponding chamber 311. This allows the entire system to simulate the coupling effect of multiple aging factors synchronously or stepwise under the same equipment architecture, thereby effectively improving the accuracy of the aging test results in predicting the actual high-altitude service performance of the sensing terminal and the reliability of the assessment.

Various modifications and variations can be made to the present invention by those skilled in the art.
